A-share real estate stocks rose by 100 shares, and institutions: the turnover of new houses and second-hand houses in many places improved from the previous month.

On May 15th, after the opening of A shares, the real estate index kept rising. As of press time, the real estate index rose by 3.7%, with 109 constituent stocks and over 100 stocks.

Among them, Everbright Jiabao, Tiandiyuan, Cinda Real Estate, Yunnan Chengtou and I Love My Family have daily limit, Binjiang Group has increased by 9.87%, special service has increased by 8.41%, Huafa shares have increased by 7.51%, China Merchants Shekou, Poly Development, China Communications Real Estate and Tianbao Infrastructure have increased by more than 6%, and Nanguo Real Estate, Vanke A, Beijing Investment Development and Daming City have recorded 5%.

In the news, it is reported in the market that relevant departments are considering a plan to let local governments all over the country buy unsold stock houses. The scheme may allow banks to provide loans.

In addition, the housing purchase restriction that has been implemented for 14 years has become history in many cities. Chengdu, Hangzhou, Xi ‘an and other hot cities completely canceled the purchase restriction, and several cities in Guangdong Province improved the architectural design on the supply side and reduced the pool area, which helped to enhance market sentiment to some extent.

From the perspective of market performance, according to the data of 58 Anjuke platform, after Xi’ an lifted the purchase restriction on May 9, the online second-hand housing search fever increased by 22% compared with the previous day; New homes rose by 39%.

Last week, the transaction volume of second-hand houses in Shenzhen increased by 201% month-on-month, and the number of houses for sale declined for three consecutive weeks. A real estate in Xihu District of Hangzhou sold 50 million yuan at the speed of light in a single day, and foreign buyers organized a group to "bargain-hunting".

Debon Securities’ latest weekly report on the real estate industry shows that the transactions of new houses and second-hand houses in many places have improved month on month. Last week (May 6 -10), the cumulative land transactions in the top 100 cities were -27.32% year-on-year. Last week, the planned construction area of residential land in 100 large and medium-sized cities was 2,241,200 square meters, a cumulative year-on-year increase of -27.32%. Among them, the planned construction area of residential land in first-tier cities was -39.64% year-on-year, and the planned construction area of residential land in second-tier cities was 327,500 square meters, which was -15.70% year-on-year.

The cumulative year-on-year decline in the sales area of commercial housing in 30 large and medium-sized cities has narrowed. Last week, the transaction volume of commercial housing in 30 large and medium-sized cities was 1,906,700 square meters, with a cumulative year-on-year ratio of -42.62%. Among them, the transaction volume of commercial housing in first-tier cities was 411,000 square meters, with a cumulative year-on-year ratio of -37.59%, and that in second-tier cities was 980,700 square meters, with a cumulative year-on-year ratio of -43.73%.

Guoxin Futures believes that from a national perspective, at present, housing-related purchase restrictions are only relatively strict in the core urban areas of a few areas such as Beijing and Shanghai. In the later period, the demand-side favorable policy, which mainly cancels the purchase restriction policy, will become the main trend nationwide. However, the purchase restriction policy in the core areas of first-tier cities is completely cancelled or still relatively cautious. Of course, there is still some room for optimization in the later stage.

From the perspective of real estate policy orientation, the high probability is still loose, highlighting "marginal optimization and continuous fine-tuning". Judging from the characteristics of real estate, the investment attributes of some commercial housing may be more prominent. Compared with this, the residential property of affordable housing may be more significant. From the perspective of real estate enterprises, it may usher in further adjustment. Head housing enterprises with stable operation and good reputation are expected to get greater support in financing and government policies. In contrast, some small and medium-sized real estate enterprises are under certain pressure. From the perspective of real estate prices, it is expected to go up structurally.

Sudden death at the age of 34: How far is "sudden death" from us?

Recently, the sudden death of a 34-year-old graduate student has sparked heated discussions. Originally, I graduated in half a month, but I didn’t expect to fall in the study room in the early morning and never get up again. ……

The family members of the deceased once voiced that they had checked and confirmed that there was a heart problem in May this year, and the examination result was "arrhythmia of coronary heart disease".

While lamenting the fragility of life, we must understand the preciousness of life, pay attention to our health, and our own health problems must not be ignored. This small series and everyone popularize coronary heart disease, including how to prevent coronary heart disease and first aid in emergencies.

# Talk about health on Thursday

9: 00 a.m. on January 20th.

Health lecture hall on the first floor of 5G medical ward building in the First Hospital of Medical University

Coronary heart disease (CHD) is a heart disease caused by myocardial ischemia and hypoxia caused by the blockage of blood vessels (coronary arteries) supplying heart nutrition by atherosclerotic plaque (or thrombus).

Coronary heart disease is prone to:

1, middle-aged and elderly people, smokers, hypertensive patients, diabetic patients, obese people.

2. Bad lifestyles include smoking, unreasonable diet (high fat, high calorie, etc.), lack of physical activity, excessive drinking, and social and psychological factors.

3. Irreversible risk factors are: gender, age and family history. In addition, it is related to infection, such as cytomegalovirus, chlamydia pneumoniae and helicobacter pylori.

4. The onset of coronary heart disease is often related to seasonal changes, emotional excitement, increased physical activity, satiety, heavy smoking and drinking.

What are the common symptoms of coronary heart disease?

There is pain behind the sternum or in the precordial area, which sometimes involves the shoulder, the inside of the left arm, the fingers and the pharynx;

Pain can be manifested as burning, soreness, tightness or feeling of oppression;

Pain is induced by intense emotional fluctuation, strong physical activity, full meal and cold.

Pain can generally be relieved in 3-5 minutes;

If the attack is frequent and lasts for a long time, you should be alert to "acute myocardial infarction" and seek medical advice as soon as possible;

Some patients have no obvious discomfort.

How to prevent and treat it?

1. Patients with coronary heart disease should have a low-fat diet, exercise properly and maintain emotional stability in their daily lives.

(1) usually drink warm water;

② Eat more fresh vegetables and fruits, and pay attention to a low-salt, low-sugar and low-fat diet;

③ Don’t smoke and drink, pay attention to rest, and don’t stay up late;

④ Exercise properly every day, control your weight, relax your stress and maintain a happy mood;

⑤ Once accompanied by hypertension, hyperglycemia and hyperlipidemia, long-term medication control is needed.

2. Women are over 60 years old and men are over 55 years old. It is recommended that patients take low-dose aspirin regularly. The treatment methods of different patients are different, so it is necessary to adopt correct methods for symptomatic treatment. Please follow the doctor’s advice for drug use and treatment.

Once coronary heart disease occurs, how to give first aid?

1. First of all, stop activities and have a rest immediately.

2. Unbutton the buttons while evacuating the onlookers to ensure adequate oxygen supply.

3. Use spare emergency medicine in time, and call 120 emergency number at the same time. Never move the patient at will.

Nitroglycerin is the first choice for first aid of coronary heart disease? Or quick-acting rescue pills?

Nitroglycerin should be the first choice for acute angina pectoris.

When nitroglycerin is ineffective, quick-acting jiuxin pills can be used.

When nitroglycerin is contraindicated or intolerant, quick-acting Jiuxin Pills can be used.

# Tips

Nitroglycerin must be taken sublingually; Must be taken in a sitting position; Take it continuously for up to three times; Change the medicine in time. Nitroglycerin must be stored in a cool place, and it will be invalid for 3-6 months after opening the bottle cap. Borneol in Suxiao Jiuxin Pills is easy to volatilize.

I found a new bacterium. Can I name it Cyndi Wang?

Original Tommy guoke

If you don’t know the friend below, call him "long-haired black pig".

Actually, it’s called curly boar, wikimedia commons/ Magalh?es

We might as well call the following clump of plants "Carex macrophylla".

Actually, it’s bottle grass in the mountains, wikimedia commons/ NoahElhardt

Even without professional knowledge, we can easily name animals and plants that are visible to the naked eye according to their appearance, such as small red flowers, big orange cats and so on.

But there are many microbes in the world! They are invisible to the naked eye, and their features are not as obvious as those of animals and plants. How do you name them? Is it like the joke that the newly discovered bacteria are named after their sweetheart?

Have a surname and be famous.

The long-haired black pig and the big tube grass mentioned just now are nicknames casually, but in formal occasions, we should use scientific names and big names.

The scientific name of a species is written in Latin and consists of two parts: the first half is the generic name, which is equivalent to the surname of a person, and a surname is the family name; The latter part is a name, which is equivalent to a person’s name and is used to identify an individual.

In order to explain this matter more interestingly, we also drew a cartoon. Welcome to come in and have a look →.

Theoretically, if a scholar discovers a new kind of bacteria/fungi, as long as it doesn’t duplicate the existing bacterial name, it won’t cause ambiguity, and it doesn’t violate the law, morality, public order and good customs. Basically, he can name whatever he thinks of, and the naming right belongs to the scholar who first reported it.

It’s kind of cool to think about it.

The first rule of naming: look at the face

Naming according to the shape is the most common naming method, which is very intuitive! The most representative is the famous Staphylococcus aureus.

The scientific name of Staphylococcus aureus is Staphylococcus Aureus. It is a string of Latin names, meaning "bunches of grapes" and "round fruits". Do you think it is as round as a grape?

Figure CDC

And its "name" means "golden yellow" The photo above has been dyed, and it is actually golden in a Petri dish:

Figure wikimedia commons

Staphylococcus aureus in "Working Cell" and "Working Cell"

This naming method is as straightforward as a boy who is 1.9 meters tall is really called a "tall man".

They also belong to this category.

Staphylococcus haemolyticus: This bacterium can make hemolysis circle around the colony on the culture medium containing blood components.

Bacillus cereus: The colony is rough in appearance and resembles solidified wax drops, which often causes food poisoning.

Fusarium spp.: The spores of this kind of fungi are crescent-shaped and resemble sickle, which can cause plant diseases and infect people or animals.

Naming Rule 2: Check the account.

We often use place names to identify a person, such as Beijingers, Asians and Earthlings. This method can also be used on microorganisms: see where it is.

In 2001, the Medical College of Hong Kong University reported a brand-new pathogenic bacteria for the first time. The strain was isolated from the blood and pleural pus of a patient with liver cirrhosis admitted to hospital due to high fever and shortness of breath [7]. Because it was isolated for the first time in Hong Kong, it was named Laribacter hongkongensis.

Some bacteria have a more unique "hukou", for example, Escherichia coli, and the hukou: large intestine.

Escherichia coli wikimedia commons/ Eric Erbe magnified by 10000 times

The official name of Escherichia coli is Escherichia coli, and it is worth mentioning that "Ehi" comes from a person’s name.

In 1885, German doctor Theodor Escherich isolated the bacterium from feces. To commemorate the great discovery of Dr. Escherich, in 1919, the strain was officially named "Escherichia" [6].

They also belong to this category.

Nocardia cyriacigeorgica in St. George’s Church: The bacterium was first isolated from the mural of the church. Because the church is located in a small town called Gelsenkirchen in Germany, it is sometimes translated as Nocardia Gelsenkirchen.

Leifsonia shinshuensis: "shinshu" refers to shinshu, Japan, and is the old name of Nagano, where it was first discovered.

Bacillus nanhaiensis: It was first isolated from oysters collected in the South China Sea by Chinese scholars in 2011, and later it was renamed as "Fictitious nanhaiensis".

Rule 3 of Naming: Name by "sin"

All children in our country should be vaccinated with DTP, in which "white" refers to diphtheria, a once murderous disease. This disease can cause myocarditis or systemic poisoning, and most patients will have a gray-white film on their throat, so this disease is called "diphtheria".

A grayish white membrane grows near the tonsils of diphtheria patients. wikimedia commons/Dileepunnikri.

The initiator of diphtheria is a long rod-shaped bacterium, which is also called "Corynebacterium diphtheriae".

They also belong to this category.

Rabies Virus: the pathogen of rabies; In addition to infecting humans, it can also infect mammals such as dogs, wolves and cats.

Yersinia pestis: the pathogen of plague (Black Death); The strain can infect rodents, mainly rodents, and spread to humans through rat fleas.

Streptococcus pneumoniae: a kind of cocci arranged in a short necklace, which often causes pneumonia in children and the elderly.

Neisseria gonorrhoeae: Neisseria gonorrhoeae, formerly known as Neisseria gonorrhoeae, can cause purulent infection of urogenital system and is one of the common sexually transmitted diseases, commonly known as gonorrhea.

Naming Rule 4: Name after people and institutions.

It is true that the newly discovered bacteria are named after their lover’s name, which belongs to the romance of microbiologists.

Louis Pasteur is one of the founders of microbiology. In order to express his respect and commemoration, in 1887, people really named a brand-new genus (equivalent to a big family) Pasteurella.

Up to now, Pasteurella "Junding Xingwang" has included 31 species and 4 subspecies, many of which are zoonotic pathogens, which coincides with some of Pasteur’s contributions (research on rabies and anthrax). I don’t know if Father Pasteur is happy or speechless.

Pasteur: I should still be happy, right? wikimedia commons/Paul Nadar

Examples of naming microorganisms after institutions or groups are no problem.

In 2010, a bacterium named Yimella was discovered [5]. YIM is the acronym of Yunnan Institute of Microbiology, and it is also the place where this bacterium was first discovered and studied. Yimella literally translated it as "Yunnan Institute of Microbiology". It’s a bit of a collective merit.

They also belong to this category.

Shigella flexneri: one of the pathogens of bacillary dysentery. The first half of the name commemorates Japanese bacteriologist K. Shiga, and the second half commemorates American bacteriologist Simon Flexner.

Rickettsia: the pathogen of typhus and trench fever. Howard Taylor Ricketts, a young American scientist, was unfortunately infected by him and gave his precious life during his research. In order to commemorate his contribution and sacrifice, later generations named it after him.

Legionella: During the Veterans’ Congress held in Philadelphia, USA in 1976, some veterans suffered from pneumonia, which was later confirmed to be caused by a new bacterium named Legionella.

Rule 5 of naming: flip through fairy tales

There’s a genus called Agaricus bisporus, which is very domineering, right? Friends who are familiar with western mythology may know that there is a god in Roman mythology with two faces: the front face looks ahead and the future can be seen; Looking back, you can see the past.

Two-faced gods in Roman mythology: wikimedia commons/ Loudon dodd.

Are the members of the genus Agaricus also very distinctive? No, it looks like an ordinary capsule (Bacillus) or ball (cocci).

However, most members of this genus have one thing in common: they can switch the two forms of Bacillus and cocci in different culture environments. This may also be one of the reasons why it was named like this.

They also belong to this category.

Mycobacterium chimaera: "Chimera" originated from a monster in Greek mythology. It has the head of a lion, the body of a goat and the tail of a python. Mycobacterium Chimera has obvious mixed genetic characteristics, hence its name.

Asgardarchaeota: Some scholars think that this kind of bacteria may be the common ancestor of all life on the earth. What’s more, they named the members of this kind of bacteria Odinarchaeota, Thorarchaeota, and Loki archaea in one breath … and they got together the family photos of the Nordic gods. By the way, these archaea have not yet been alive, and I sincerely hope that there will be a big coffee among the readers of the shell to clarify this process and name it "Ragnarok".

Guokr

In fact, there are many other naming methods, so I won’t list them here. In any case, the naming of microorganisms is a serious process. In the short name, there are both lessons of blood and tears, as well as the exploration of nature, which is an immortal testimony of our human wisdom and courage.

24 hours in the emergency department

  Xinhua News Agency, Taiyuan, August 18th (Reporter Fan Xinyang, Zhang Zhe) From early morning till late at night, the emergency department never "closes". Whether it is the first aid in the middle of the night or the ward round in the morning, every moment of persistence is awe and commitment to life.

  August 19th is the Physician’s Day in China. The reporter recorded the 24-hour working status of the emergency department of Shanxi Bethune Hospital (Tongji Shanxi Hospital) in Taiyuan City, Shanxi Province.

  17 o’clock

  5 pm is the time when many people are ready to get off work, but for the emergency department, the real busy period has just begun. At this time, outside the emergency room, patients have begun to line up in turn, and emergency doctors respond to every "critical and urgent" patient quickly and orderly, guarding every life in need with professionalism and dedication.

  18 o’clock

  At 8 am and 6 pm, it is the emergency shift time. Each round of emergency doctors need to be on duty for about 12 hours, and there are usually a new group of patients from 8 am to noon. The emergency department in the afternoon is a little quiet, and the emergency department enters a busy period at 6 pm.

  19 o’clock

  At 7 o’clock in the evening, the head nurse organized new nurses and intern nurses to study the theoretical knowledge of emergency and practice training in the conference room, and one of them was reporting her own topic.

  20 o’clock

  Entrusted by the emergency doctor, the nurse, together with the patient’s family, accompanied the patient to do brain CT. In the emergency department, all examinations, instruments and equipment are on-line all the time to protect patients’ lives and health at all times.

  <扑克游戏> Blackjack <时间> 9 p.m./nine o’clock at night

  Unlike other departments that sort out cases at fixed points, in emergency, doctors will sort out cases at any time and recycle them to the medical record department in time. Medical record recovery plays an important role in protecting patients’ privacy, improving medical quality and safety, and assisting medical research and education.

  22 o’clock

  At 10 o’clock in the evening, the nurse first established venous access for patients entering the emergency room.

  23 o’clock

  At 11 o’clock in the evening, an 88-year-old man suddenly suffered from renal failure in the emergency room. The emergency doctor performed femoral vein puncture for him and performed hemofiltration at the bedside.

  0 o’clock

  The emergency room ward in the middle of the night is different from the wards of other departments in the hospital. New patients may flood in at any time, and existing patients may also have new emergencies. In the early hours of the morning, compared with the tranquility of other wards, emergency doctors, nurses and patients’ families are still busy in the ward.

  1 o’clock

  At 1 o’clock in the morning, an old man in the emergency ward was diagnosed with intracranial infection, and the emergency doctor called the doctor on duty in the neurology department for consultation. According to the regulations, under normal circumstances, patients can’t stay in the emergency department for more than 24 hours, so emergency doctors need to find the most suitable treatment plan for patients within a limited time. Call doctors from all departments of the hospital at any time to assist in diagnosis and treatment, in order to facilitate the patient’s subsequent hospitalization.

  2 o’clock

  The early morning is a busy time in the emergency surgical rescue room. Patients injured in unexpected situations such as car accidents were sent to the emergency department. After transporting a patient injured in a car accident, the 120 ambulance team is cleaning up the blood stains on the ambulance.

  3-4 o’clock

  The emergency room in the middle of the night is rarely quiet. In the corner of the emergency hall, there are several stretchers on standby. "We definitely hope that there will be fewer patients, and it is best not to use these stretchers." An emergency doctor said.

  5 o’clock

  At dawn, the emergency department returned to some tranquility, and the emergency doctor on duty finally had time to lie in the rest room for a while, preparing for the morning shift and rounds.

  6 o’clock

  At 6 o’clock in the morning, the emergency doctor on the night shift finally had a chance to eat something to replenish his strength. The doctor on duty was sending breakfast pancakes to the lounge and informing other doctors and nurses in the WeChat group to take time to eat.

  7 o’clock

  At 7 o’clock in the morning, many people just got up to go out to work, and emergency doctors have been on standby for a long time, always ready to deal with emergencies. At this time, the instruments in the emergency ward are fully on standby, ready to provide services for new patients. The difference between the emergency department and other departments is that all kinds of rescue equipment are concentrated here, and you can find a transfer ventilator, Saab resuscitator, electrocardiogram machine and so on in one ward. Emergency doctors not only need to respond quickly, but also operate these devices skillfully, and strive to rescue patients effectively in the first time.

  8 o’clock

  At 8 o’clock in the morning, the emergency doctors on the night shift began to hand over to the doctors on the day shift, from the triage desk, nurses to doctors to introduce the existing patients in the ward in turn. Beginning with the handover, but not limited to the handover, the emergency director usually discusses the patient’s situation and the follow-up treatment at the handover meeting.

  9 o’clock

  After handing over the basic situation, two classes of doctors will come to the ward of the emergency room to further confirm and discuss the patient’s data and complete the final handover between day and night.

  ten o’clock

  The patients in the emergency observation room are a relatively minor group in the whole emergency ward. Compared with other emergency patients, they may be lucky enough to leave the emergency room after infusion.

  11 o’clock

  Near noon, several workers were in the emergency room, and their arms were injured while working on the construction site. Among the patients admitted to the surgical emergency department, people engaged in high-risk manual labor account for a relatively high proportion.

  12 o ‘clock

  Family members of patients bring hot porridge cooked at home for patients with mobility difficulties. Family care and love is the most simple and warm scene in the emergency room.

  13 o’clock

  At 1 o’clock in the afternoon, outside the emergency room, the patient’s family hurriedly pushed a patient. The patient was unconscious and lost consciousness. The nurse hurriedly pushed the patient into the emergency treatment room and quickly informed the emergency doctor.

  14 o’clock

  120 Emergency Center personnel go to the triage desk to connect the patient information and situation with the nurse after completing the patient transportation. Race against time and life, the shirts of 120 ambulance workers have been soaked with sweat.

  15 o’clock

  In the afternoon, the emergency department is a relatively relaxing time, and it is rare to be quiet in the emergency department. Families in twos and threes rest in the empty corridor.

  16 o’clock

  If there are no new patients in the emergency rescue room, nurses will use their spare time to practice the rescue practice skill-"simple respirator assisted breathing", which can assist patients with ventilation disorders to increase ventilation and improve ventilation function.

  Through the moments recorded by the camera, we can see that whether it is waiting in the morning or racing against time in the evening, the emergency department doctors and nurses are always in the front line, striving for precious time for every life in need with selfless dedication and professional skills.

  On the occasion of China Physician’s Day, I pay tribute to these medical workers who are guarding the front line of life.

Beijing Municipal Center for Disease Control and Prevention issued a reminder:

Fever, sore throat, rash

Watch out for scarlet fever!

May 24 th

China CDC also issued a reminder:

Scarlet fever enters the high season!

What is scarlet fever?

The disease control department reminded that it is necessary to focus on the prevention and control of infectious diseases such as scarlet fever in the near future. Scarlet fever is a legal class B infectious disease in China, and there is no vaccine to prevent it at present.

Scarlet fever is an acute respiratory infectious disease caused by group A β hemolytic streptococcus infection, which can cause tonsillitis, angina and other upper respiratory infectious diseases in children. Its complications, rheumatic fever and acute glomerulonephritis, seriously endanger the health of adolescents.

Cough and sneezing can spread it.

Patients and asymptomatic carriers are the main sources of infection.

droplet transmission

The route of transmission is mainly droplet transmission, such as coughing and sneezing.

Spread of contaminated equipment

Accidental contact with utensils contaminated by bacteria can also be infected.

Children aged 2~10 years old are easily infected!

The population is generally susceptible, and kindergarten children and primary school students are the main groups. Strong immunity can be obtained after infection, and it is less likely to be infected with the same serotype pathogen again.

Incubation period: 1~12 days, mostly 2~5 days.

Clinical manifestations of scarlet fever

The early symptoms of scarlet fever are atypical, mainly fever and sore throat. After 2-3 days of fever, the following typical manifestations will appear:

1. Diffuse needle-tip-sized rash all over the body, which fades and itches slightly.

The child starts to break out within 24 hours after fever, starting from behind the ear and neck, and then quickly spreading to trunk and limbs;

A typical rash is evenly distributed on the skin, faded by pressure, accompanied by itching, and the skin will desquamate after fading.

2. strawberry tongue

Let the child open his mouth wide, focusing on whether the child’s tongue is like strawberry or bayberry;

Observe the child’s tonsils, whether there is tonsil inflammation, congestion or purulent exudation.

3. Flushed face and pale mouth.

The child’s face is bloodshot, but the lip is not as obvious as the face, and the lip looks like a white circle.

Most of the symptoms of scarlet fever are mild, but a small part can cause damage to the heart, kidneys and joints!

Image source: Beijing Center for Disease Control and Prevention

How to prevent it?

At present, there is no vaccine to prevent scarlet fever, and the following can also be effectively prevented:

Step 1 manage the source of infection

If the child is diagnosed with scarlet fever, he should avoid going to school, seek medical treatment in time, and return to school after he is ill;

Appliances contaminated by patients can be boiled and disinfected. Furniture desks should be scrubbed and disinfected with soapy water or disinfectant. Items that cannot be scrubbed can be exposed to the sun for 1~2 hours.

2. Cut off the route of transmission

Pay attention to personal hygiene, wash your hands frequently and ventilate indoors frequently.

During the period of high incidence of scarlet fever, try to reduce taking children to places with dense crowds and poor ventilation, such as wearing masks as much as possible.

3. Improve children’s immunity

Proper outdoor exercise, a balanced diet and adequate sleep can all improve immunity!

Scarlet fever enters the high season.

Do a good job of self-prevention

In case of suspicious scarlet fever symptoms.

Seek medical attention as soon as possible.

Forward! Spread! Remind more people!

Henan Communist Youth League comprehensive arrangement, please indicate the source.

Knowledge short video science popularization is more heart-warming.

  "Teacher Lu playing with bones" Lu Jing put the bones of fish head, braised chicken and Beijing roast duck together into a whole skeleton, creating a kind of "visual sense of paleontology museum".


  Dai Jianye, a professor of "Debris Flow", told the story of Li Bai, Du Fu and Gao Shi joining hands to visit famous mountains, visit immortals and refine the elixir, which reappeared the prosperous time of the Tang Dynasty.


  Gong Gongjun, who only made a noise but didn’t show up, took everyone to visit every corner of the Forbidden City and quoted the classics to tell the cold knowledge and little interesting things of the Forbidden City.


  With the development of short video platform, more and more content creators have emerged to share and spread knowledge. They are popular science experts who have knowledge, love sharing and are familiar with skills. These high-quality content supplies meet and create a huge demand for knowledge.


  Professor Hu Baijing, Executive Dean of School of Journalism, Renmin University of China, believes that the rise of short video platform has promoted the expansion of knowledge production from elite to the public, making knowledge more personalized and scene-oriented, and at the same time making it possible for knowledge to be universal, knowledge to be promoted, and knowledge to be shared and co-created.


  


  Small but refined, making universal knowledge close to reality.


  "Tang Xuanzong released Li Bai from the court, that is, he was given a sum of money to get rid of him: you are not cut out to be a prime minister. Li Bai went to Luoyang from Chang ‘an, and Du Fu was a fan of Li Bai. Li Bai was kind enough to let him meet him. After meeting him, he admired Li Bai to death. I don’t know whether Li Bai plays cowhide well or is charming. Anyway, Du Fu listened to his words and started from Luoyang, Henan Province to Hebei and Shandong with his eldest brother. What for? Looking for immortals, picking fairy grass and refining elixir, I met Gao Shi halfway … "This is the story that happened in 744 AD and was called the meeting of the sun and the moon in China literary world by Wen Yiduo. Only Confucius can match it when he saw Lao Zi.


  Although it doesn’t sound formal, this remark is by no means a fabrication by Dai Jianye, a professor at the College of Literature of Central China Normal University. The experiences of Li, Du and Gao in seeking immortality and monasticism are reflected in several poems of Du Fu. Dai Jianye lamented that it was a generation of romantic people.


  When this lecture video was put on Tik Tok, Dai Jianye didn’t know what the latter was. More than a year later, he became Professor online celebrity known as the Debris Flow. The Tik Tok has nearly 4 million fans and tens of millions of likes.


  The "big family" living in Hefei is a lawyer with nearly 10 years of financial work experience. In her spare time, she uses short videos to give netizens common knowledge of popular science and economics.


  The "treasure family" found that the public is very curious about knowledge, but many people have no chance to receive economic education, lack basic knowledge of wealth, and have no concept of risks and benefits. If the public can learn more about economics, they may be able to avoid some losses. Some netizens left a message under the short video she posted: "Fortunately, I saw that you were not fooled by the Ponzi scheme, and my friends around me pressed hundreds of thousands of yuan on a financial platform."


  In the era of short video, knowledge levels are diversified and symbiotic, including authoritative scientific theories, life tips and workplace office skills to meet the different knowledge needs of different audiences. The sharers of knowledge are not necessarily high-ranking experts and scholars, but also life experts who are familiar with their own fields.


  Compared with the traditional graphic form, short video communication knowledge has four characteristics: immediacy of knowledge dissemination, personalization of knowledge presentation, manifestation of invisible knowledge and popularization of complex knowledge.


  Zhao Yan, President and Editor-in-Chief of China Science Newspaper, said that a short video of 15 seconds to 1 minute condensed the serious knowledge on weekdays and passed it on to the audience in a more visual form, which changed the boring appearance of knowledge and narrowed the distance between the public and cultural knowledge. Knowledge sharing and linking with short videos not only broadens the boundaries of knowledge, but also brings knowledge inclusiveness close to reality.


  Promote the value shift of Internet content industry. 


  In the eyes of knowledge creators, short videos have become the primary tool for them to spread and exchange knowledge.


  Xiang Bo, who works as a chemistry teacher at Guangyuan Middle School in Sichuan Province, said that his own class could only affect 40 or 50 students in the classroom. "But now I am a teacher shared by more than 6 million fans. Making good use of communication tools can eliminate the time and space barriers of knowledge dissemination and light up more people’s enthusiasm for chemistry. "


  Lu Jing, an associate researcher at the Institute of vertebrate paleontology and Paleoanthropology, Chinese Academy of Sciences, feels that doing popular science on short videos is a "new and wonderful experience". Before that, she didn’t expect that the mobile internet platform could tilt resources to serious knowledge creators and content like her. Short videos made her find a hyperlink to share knowledge with the world, and the feedback from "fans" became her motivation to persist in doing popular science. "I feel that short videos make the way to do knowledge on the Internet wider and wider."


  The purpose of people’s initial use of short video software is mostly entertainment and leisure, but in a highly fragmented and entertaining viewing environment, it is easy to have a sense of emptiness and aesthetic fatigue after a long time. The emergence of knowledge-based content, like a clean stream, can fill the gaps in people’s hearts.


  Wang Xiaohong, a professor at Communication University of China, pointed out that with some Internet platforms successively launching measures to spread service knowledge, "knowledge content has gained unprecedented attention in the Internet industry. This trend reflects the upgrading of Internet content from single entertainment to knowledge. It can be said that the short video platform has driven the value shift of the Internet content industry. "


  For users, short videos break the original time-space limitation of knowledge intake, allowing people to use their spare time to study anytime and anywhere. At the same time, short videos present knowledge in the form of concise and clear knowledge points, and ignite users’ interest in further in-depth learning.


  Therefore, on the one hand, short video greatly reduces the threshold and difficulty of knowledge reception, mobilizes the enthusiasm of the public to create and disseminate knowledge, and realizes co-creation; On the other hand, short videos take social interaction as a link, breaking down the barriers of knowledge dissemination, allowing knowledge to reach more people and realize sharing.


  Provide a better environment for knowledge content creation


  "Information creates value. Among the many values created by information, the value of knowledge dissemination is the highest." Zhang Yu, vice president of ByteDance, believes that continuous investment in knowledge content will benefit the sustained and healthy development of the entire Internet content industry.


  "As a platform or technology, if high-quality content is not occupied, then harmful content will be occupied." Dai Jianye said, "Short videos have both pictures and sounds, and you can also add words, which is definitely a very good way to spread. Algorithms and traffic tell us what kind of articles and videos are the most popular and what kind of knowledge people like, which not only enables the author to tailor them accurately, but also enables the network to deliver them to the door regularly and quantitatively, which profoundly affects the production of knowledge. Those popular knowledge will be churned out in large quantities, but the neglected knowledge will not be produced. "


  Dai Jianye’s viewpoint is being verified by practice. At the "2019DOU Knowledge Creator Conference" held in Beijing a few days ago, Zhang Yu introduced that as of December 2, 2019, the number of knowledge content creators with over 10,000 fans in Tik Tok had exceeded 74,000, and a total of 19.85 million high-quality knowledge short videos were created, with a cumulative broadcast volume of more than 1.9 trillion; Each short video of knowledge has reached nearly 100,000 people.


  At present, all major short video platforms have built their own content pools, focusing on providing young people with high-quality content such as teaching, calligraphy and painting, parenting education, human history, traditional culture, handcrafting, natural science popularization and so on. For example, the Encyclopedia, a knowledge label area initiated by Aauto Quicker, and the DOU Knowledge Plan and the Non-legacy Partner Plan initiated by Tik Tok in conjunction with the Science Communication Bureau of Chinese Academy of Sciences, etc.


  However, at present, the overall proportion of these contents is still low, and the total amount is still insufficient. In the future, various short video platforms will continue to exert their efforts to provide a better environment and more support for knowledge content creation.


  In addition, regarding the view that short video learning is fragmented, Chen Zheng, a teacher at the National Physics Experimental Teaching Demonstration Center of Beijing Jiaotong University, said in an interview with the media: "Short video really can’t achieve the effect of systematic teaching, nor can it train professionals, but at least it can do one thing, that is, open a door. I teach physics, and my goal is to show some basic world outlook and methodology to the audience, especially teenagers, through these fragmented puzzles. When they collect enough’ fragments’, they master their internal connections and can spell out a complete picture of the world. "
